Design of electronic subsystem for reduced gravity impact simulator
Ostrý, Lubomír ; Hadaš, Zdeněk (referee) ; Věchet, Stanislav (advisor)
The focus of this thesis is development of an electronic subsystem for reduced gravity impact simulator. The research part of this thesis firstly covers methods used for simulation of microgravity or reduced gravity and compares them. Another part of research focuses on three selected potential approaches to creating the electronic subsystem for this device. The second, practical, part of this thesis describes the design and development of the electronic subsystem. The foundation of the electronic subsystem is a control unit which has been developed on the basis of an STMicroelectronics microcontroller. Using the control unit, the electronic subsystem measures pressure, position, acceleration and force in the system. Another task of the control unit is control of a stepper motor. Integration of individual elements into the electronic subsystem is described both in terms of software and hardware. Furthermore, a graphic user interface program for PC has been developed as a means to interact with the system. In the final part of the thesis, the operation of the electronic subsystem is described and lastly, the electronic subsystem is evaluated.

Data storage architecture for manufacturing processes
Bobák, Petr ; Kaczmarczyk, Václav (referee) ; Holek, Radovan (advisor)
The aim of the thesis is to develop a concept of an information system for collecting and processing data from an industrial process, which will be a part of a complex monitoring system as a whole chain from the sensor to the information system. The thesis briefly describes decision making process of a HMI device selection – Weintek cMT-SVR-100 visualization server, which is able to transfer data acquired from PLC’s via Modbus TCP over Ethernet to a remote MySQL database in the internet. Its main properties and output data structure was described. The thesis presents data and process model of the database and a web application design as a user interface. The web app allows users to access the system via general web browser at any platform and/or device. The thesis also presents testing of the system and its results.

Measurement and analysis of dynamic properties of rotating machine parts
Gofroň, Vojtěch ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
Diploma thesis focuses on measurement and analysis of shaft motion, torque, angular velocity and vibration. First part of the thesis deals with general issue of acquiring a digital signal. Next part describes suitable sensors for each measurement type, and data acquisition hardware. The last theoretical part describes methods for measurement data analysis and vibration diagnostics. Practical part of the thesis describes shaft motion and torque measurements made on laboratory equipment, and vibration measurement made on real machine system. Each measurement includes measurement data analysis and evaluation.

Digital Storage Oscilloscope
Piši, Daniel ; Keprt, Jiří (referee) ; Havránek, Zdeněk (advisor)
This bachelor project deals with design and implementation of PC based USB digital storage oscilloscope. The aim of presented measurement instrument is to fill the space between amateur constructions and expensive proffesional oscilloscopes. In addition to good measurement parameters and affordable price wants to engage by free licence and originality solution. The concept of whole construction shows measurement instrument as a system of independent modules bringing new possibilities of extending functionality.

Measurement module with simultaneous-sampling A/D converter
Křížek, Miroslav ; Beneš, Petr (referee) ; Havránek, Zdeněk (advisor)
In this work is designed programme unit for acquisition analog acoustic signlas from sensors. There is used accurate A/D converter ADS1287 by the company Texas Iinstrument with resolution of 24 bits to digitizing these signals. There is used 32-bit microprocessor AT91SAM7S64 by the company Atmel to control this A/D converter and sending digitized data to PC. This microprocessor has implemented USB interface. By force of developmental programme units whit microprocessor and A/D converter is produced programme for microprocessor in developmental setting IAR Embedded Workbench IDE 5.0 and simple aplication for PC in setting Borland C++ Builder. Both of those programs are in language C++. Rate of sampling is 26 kHz. On the basis is realized programme unit USB-ADC whit microprocessor and A/D converter.
